This program will remove Reseaus from Viking, Voyager, and Mariner images.
The Reseaus are removed using either bilinear interpolation of the
surrounding pixels or by simply putting NULLs in the portion of the
image around the Reseau location of the input image. The ACTION
parameter is used to tell the program which of these two actions to
take. The user should input the size of the box around the Reseau that
will be modified. SDIM and LDIM are the sample and line dimensions of
the box around the reseau. RESVALID is used to determine whether the
program will check the reseau valid flag for nominal reseaux before
removing the reseau. If RESVALID is NO, the program will not check
the reseau valid flag for nominal reseaux and all the reseaux will be
removed except invalid nominal positions. If RESVALID is YES, the
program will check the reseau valid flag that is output from the
findrx program. If the flag is 0, the program will not remove that
reseau. If the flag is 1, the reseau will be removed. If the flag is
-1, indicating an invalid nominal position, the reseau will not be
removed in any case. The output cube file can be written over the
input file or a new output cube can be created. To overwrite the input
file, the TO parameter should be set to blank, " ". The "findrx"
program, which writes the Reseau locations, Reseau type, and a valid
flag to the cube file label, must be run before "remrx".
If this parameter is TRUE, the reseau valid flag will be
checked before the reseau is removed. If the reseau
valid flag is a 0 or -1, the reseau will not be removed.
If the reseau valid flag is a 1, the reseau will be
removed. Reseaus with a valid flag=-1 are never removed.
This flag indicates an invalid nominal position.
If RESVALID is FALSE, the reseau valid flag will not be
checked for nominals and all the reseaus will be removed,
except the invalid nominals. Defaults to FALSE.
